6.3.3

Reference measuring equipment shall be calibrated and traceable to a recognised national or international Standard and records maintained. 

Hi Guys 

I'm wondering what standard people are following in the U.S.

We check weigh scales daily and they have certain variances they must fall under but we are not following any particular standard and I'm having a tough time finding a standard or law that states rules for scales and/or the weights(certified by state office) that verify the scales are reading correctly.

Thanks, That was the start I needed.

Dear HACCPApprentice -

     Do you have someone check calibration from the outside, or are you using a trained personnel with certified weights do it internally? There are different standards depending on the intended use of the product's weight (retail sales versus WIP send for further processing). I have found that many smaller (10 Lb) industrial scales used in wet enviroments (like a raw poultry processing plant) can be checked for calibration, but cannot be certifed. An outside company like C.A.T. can provide useful infor along this route...

We only manufacture for other businesses, no retail. The NIST standards in HandBook 133 is what I am following. We are a small company so I will be doing NISTs detailed verification steps. I see the formulas for variances allowed per weight of unit being measured. Thanks for your help though, other might find it useful for their situation.

Check with the manufacturer of your scales too, they'll probably be able to provide you with all the info you need. They were very helpful for our small company.
